Analog pH sensor
Ceraliquid CPS41

Ceraliquid CPS41 - Analog pH sensor with refillable liquid KCl electrolyte ©Endress+Hauser

The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.

Glass electrode for applications with fast-changing medium compositions or low conductivity

Ceraliquid CPS41 is the analog high performer for pH measurement in harsh chemical applications and media with low conductivity or a considerable content of organic solvents. The sensor is designed for fast response guaranteeing you high process safety even in applications with quickly changing medium compositions.
